Good but
Although the story is some sort of spin off what has been done before ill give you credit for giving it a interesting twist. I think you can go in all different directions with this.
It's a shame that the recording for the voices lacked in quality, you should try and fix that next time you make a movie. Although it wasnt realy that irritating, it could have been far better.
The animation is nicely done but it kinde lacks in finesse. Keep working on it and I'm sure youll make something super awesome next time
Good luck!
